Title: CVD coating process for producing coatings and apparatus for carrying out the process
Inventor: ACKERMANN ULRICH
IPC: C23C16/511
Filed: 1989-09-05
Abstract: CVD coating on plane and on curved substrates, including those of large area, is carried out by generating high frequency radiation in a tubular outer conductor 3 which is emitted through an opening 4 which extends preferably axially along the outer conductor 3 into a reaction chamber 1. At least a part of the reaction gas being guided into the reaction chamber 1 through a reaction gas supplies 11 by-passing the outer conductor 3, and this causes a reactive deposition on a substrate 2 which is located below the opening 4 in the reaction chamber 1. By guiding a gas which may be argon or part of the reaction gas through the shielding 7 and using microwave resonators a plasma may be formed in the chamber which forms a reaction plasma in the region of the opening 8 on contact with the reaction gas. Alternatively the reaction gas may be excited by UV radiation occurring on gas discharge. The entire reaction gas may be guided to the reaction gas by- passing the ante-chamber in which case the different components are guided through different gas supply lines. In one embodiment using a mixture of silicon tetrachloride and oxygen as the reaction gas the oxygen is guided through the ante- chamber to the place of reaction, ie the opening, while the silicon tetrachloride is guided to the opening by-passing the sub- chamber. There may also be guided through the ante-chamber an auxiliary gas which is excited to give a plasma and this excitation is passed on through the opening to the reaction gas. The substrate is preferably quartz glass. …<IMAGE>…

Title: Apparatus for the electrolytic regeneration of etching solutions
Inventor: HARTMANN R BERND
IPC: C23F1/46
Filed: 1990-11-09
Abstract: Apparatuses for the regeneration of etching solutions which are associated directly with an etching system are known. The disadvantage of these is the fluctuating need of the etching system over a period of time in connection with the quasi-continuous working methods of the known apparatus, which essentially consists of an electrolytic cell which is used for the anodic re-oxidation of the etching solution reduced as a consequence of the etching process, and which thus leads to the known apparatus having to be dimensioned to cope with the peak needs of the etching system. In order to avoid this disadvantage, in accordance with the invention, a buffer tank (8) is provided which forms a circuit with the associated cell (2) and with pipework (9) connecting the cell and tank, the buffer tank serving as an intermediate store for regenerated etching solution, so that regenerated etching solution in the buffer tank (8) can be introduced into the anolyte circuit between the cell (2) and the etching system (1) according to need. In terms of capacity the buffer tank (8) is adaptable in the simplest manner and introduces a large degree of flexibility, particularly if additional etching systems are added. <IMAGE>

Title: Method of fabricating an elongated artefact.
Inventor: WALTERS COLIN RUSSELL
IPC: H01B13/00
Filed: 1991-07-05
Abstract: A component (10) for making A15 Nb3Sn superconducting wire is of plane-filling cross-section after removing temporary additions (6, 7). It consists of a central pillar (1) of aluminium (later replaced by tin) surrounded by a two-deep array of polygonal copper columns 2/2a containing niobium rods. Many (e.g. 61) components (10) are voidlessly stacked together and extruded. The niobium rods adopt and retain a uniform distribution with minimum intervening material. This ''sixty-one'' member retains its shape during the extrusion and is itself of plane-filling cross-section. Several of them are voidlessly stacked together and on heat-treatment of the whole, the tin diffuses over a relatively short path and hence consistently into the rods, whereby there is formed a kilofilament Nb3Sn wire.
